Identify Common Factors: Look for common factors in the first two terms and the last two terms separately.For the first two terms, 10t3 and −15t2, the common factor is 5t2.For the last two terms, 6t and −9, the common factor is 3.
Factor Out Common Factors: Factor out the common factors from the first two terms and the last two terms.10t3−15t2=5t2(2t−3)6t−9=3(2t−3)
Rewrite Using Factored Terms: Now, we have the expression in the form of two binomials that share a common factor of (2t−3). Rewrite the expression using the factored terms. 10t3−15t2+6t−9=5t2(2t−3)+3(2t−3)
Factor Out Common Binomial Factor: Factor out the common binomial factor (2t−3) from both terms.5t2(2t−3)+3(2t−3)=(5t2+3)(2t−3)
